To effectively support future 6G applications, the research community is promoting the Digital Twin (DT) technology. By creating the virtual representation of the elements, dynamics and services of physical systems, including objects and humans, DTs are expected to provide crucial support to the ambitious Sixth-generation (6G) applications, like Extended Reality (XR), autonomous driving and remote healthcare.
However, to provide such composite and complex applications, the research community on DTs have to face major research challenges, such as the definition of expressive DT representation models to manage the DTs’ dynamic nature and the design of scalable autonomous search engine among a huge number of DTs, with intensive interactions, heterogeneous communications, and billions of services.
Moreover, based on the distinct requirements of the applications, different orchestration and deployment mechanisms can be envisioned.
DTs are typically hosted in remote Cloud data centers to provide compute-intensive services but they can also migrate at the network edge to provide ultra-low-latency services and quickly interact with their real counterpart. In this context, it becomes crucial to provide optimal DT service placement in the presence of multiple edge nodes with distinct computation and storage capabilities and investigate caching policies to reuse the available DT services that can be offered to distinct clients.
So far, the literature has mainly focused on application-specific solutions for DTs, e.g., in the manufacturing field, but new holistic approaches can be devised in 6G environments. For example, revolutionary networking paradigms, like the Social Internet of Things (SIoT), can foster trustworthy and effective DT service discovery; service-centric communications, implemented by Information-Centric Networking (ICN) architectures, can facilitate the orchestration of DT at the edge and their service reuse.

Talk Title: Network Digital Twin as Key Enablers of 6G systems
Abstract: By acting as the digital counterpart of physical assets, the Digital Twin (DT) technology holds promise in different domains, ranging from smart manufacturing to e-health and automotive. Recently, the idea of leveraging the DT concept to monitor, predict, optimize and configure the behaviour of telco network elements is gaining momentum as a key enabler of upcoming sixth generation (6G) systems. The keynote provides a timely and comprehensive overview of the emerging network digital twin (NDT) concept. Nonetheless the potential benefits of NDTs, embedding them into the network ecosystem raises several concerns encompassing, among others, their lifecycle management and the network burden due to the heavy and near-real time bidirectional interactions with physical network components.
The recent literature as well as the specifications from standardization bodies will be scanned to identify the main achievements and potential open issues and to highlight future research directions. The main lesson learnt during the activities conducted within the COHERENT project (as part of the italian R&D program RESTART “RESearch and innovation on future Telecommunications systems and networks, to make Italy more smart”, funded by the European Union – NextGenerationEU) will be also shared with the
